Full of engaging stories and practical, real-world explanations, this book will help you learn everything from natural numbers and exponents to solving systems of equations and graphing polynomials.

Along the way, you’ll go beyond solving hundreds of repetitive problems, and actually use what you learn to make real-life decisions. Does it make sense to buy two years of insurance on a car that depreciates as soon as you drive it off the lot? Can you really afford an XBox 360 and a new iPhone? Learn how to put algebra to work for you, and nail your class exams along the way.

Your time is way too valuable to waste struggling with new concepts.

If you need help with algebra, this unique book is designed for you. Full of engaging stories and practical explanations, Head First Algebrawill help you learn everything from natural numbers to exponents to solving systems of equations and graphing polynomials.

Where do math issues come from?
Why is that important? Because it means that helping learners struggling with math is equal parts working on the material and working on the learner. In order to really get the learner engaged, you first have to fix the math issues that they have.Right after you tell someone that you’re writing a math book, that’s what half the people tell you. Why is that? You never hear somebody say “I’m not a history person.” They’ll just say “I don’t like history.” It says to me that people think it’s something wrong with them, not the subject.

Math study is sequential.
If you have problem with understanding a concept with addition, then you’re going to have trouble with subtraction and multiplication. So if you have a problem with Algebra, it’s going to follow you through Geometry, Algebra 2, Trigonometry, and the fact is that unless you go back and relearn the concept that is missing, there will be problems showing up in your work and it will be really hard to find the root cause.
